Reinforced concrete frame buildings with Open Ground Story (OGS) are one of the most common building configurations in urban habitat. These configurations are known to be vulnerable to seismic excitations, primarily due to the sudden loss in strength in the ground story and differential stiffness distribution throughout the structure. The differential stiffness distribution is attributed primar...

Abstract Ground shaking, whether it is due to natural or induced earthquakes, has always been a matter of concern since correlates with structural/non-structural damage and can culminate in human anxiety. Industrial activities such as water injection, gas sequestration waste fluid disposals, promote seismicity consequent ground shaking that hinder ongoing activities. Therefore, keeping mind the...

The use of ground-motion-prediction equations to estimate ground shaking has become a very popular approach for seismic-hazard assessment, especially in the framework of a logic-tree approach. Owing to the large number of existing published ground-motion models, however, the selection and ranking of appropriate models for a particular target area often pose serious practical problems. Here we s...

This paper aims to investigate the effects of motion duration on the structural seismic demands, seeking potential correlations between motion durations and structural responses at several seismic intensity levels. Three seismic intensity levels with 100years, 475years, and 2475years earthquake return periods (RPs) are first considered for correlation computations. Spectrally matched ground mot...

Induced seismicity has been a serious problem for many coal mines in the Upper Silesian Coal Basin Poland decades. The occurring mining tremors of rock mass generate seismic vibrations that cause concern to local population and some rare cases lead partial damage buildings on surface. estimation peak ground acceleration values caused by high energy is an important part hazard assessment areas. ...

Estimation of the seismic risk associated with infrastructures requires site-specific hazard studies. Further, for nonlinear time history analysis, one broadband ground motion. In modern times, physics-based simulations (PBS) deriving motion future earthquakes have been considered. The PBS helps decrease uncertainties related to estimation compared prediction equations. methods a specific frequ...

The ground motion attenuation relations have been proposed on an empirical basis and widely been used for ground motion prediction in convenient and efficient way. The accuracy of the predictions, however, is not so high given an earthquake magnitude and distance, the uncertainty of the relations has, say, 0.5 or more in a natural logarithmic standard deviation, which significantly governs the ...
